Abstract
An EL display apparatus includes pixels each including an EL element, a drive transistor, and a switch transistor, and further includes: a source driver circuit; a source signal line; a gate driver circuit; a first gate signal line; and a second gate signal line, wherein the gate driver circuit applies, to the first gate signal line, a first voltage or a second voltage, and the drive transistor is placed in a first state by the gate driver circuit applying the first voltage to the gate terminal of the drive transistor while the switch transistor is on, and is placed in a second state by the gate driver circuit applying the second voltage to the gate terminal of the drive transistor while the switch transistor is on.
